Looking for the Best Compliance and Onboarding Software

Does anyone have recommendations for effective software to streamline candidate onboarding? I work in the healthcare industry, and I usually need to gather, review, and approve more than 15 different documents. I often find myself having to collaborate with hospitals and clinicians to verify and sign off on these same documents.

Is there a user-friendly software solution that can simplify this process? I’ve tried Deputy, but it doesn’t allow for enough customization to fit my specific document flow, and the formatting for the signed documents isn’t ideal. Any suggestions?
